Trader consensus on Polymarket assigns a 38.5% implied probability to Anthropic securing the #3 AI model on LMArena's Text Arena leaderboard (Style Control On) by April's end, driven by its Claude Opus 4.6 thinking and base variants dominating #1 (1504 Elo) and #2 (1496 Elo), with Meta's muse-spark currently at #3 (1493 Elo). Google's Gemini 3.1 Pro Preview recently climbed to #4 (1492 Elo) amid ongoing battles updated 18 hours ago, fueling 28.5% odds as supply chain reports hint at further Gemini iterations. xAI's Grok 4.20 betas entered at #6/#8/#10 last week, but OpenAI's GPT-5.4 slipped to #7 after prior drops, capping it at 6.3%. Leaderboard volatility from new submissions and Elo accruals before resolution keeps the race tight among frontier labs.
